Specification forming part of Letters Patent No. 47,226, dated April1l,` 1865.`

and, useful improvements in apparatus to be used'for the raising ofliquids from great depths or to great heights, but are intended and moreespecially adapted to the raising of petroleum from deep wells,andtherefore will be described herein with particular reference thereto.

Many apparatuses have been heretofore invented consisting of variousarrangements of devieesfor forcing petroleum from wells by means of anair-blast, but have been only partially successful, and quiteunsatisfactory in their operation, for the reason that the discharge ofoil from the well was slow and tedious and in not such sufficientquantities as desired with the amount of air used.

To produce an apparatus by which the proportion of oil discharged fromthe well by means of an airblast should be made to greatly exceed thatheretofore possible by any of the apparatuses now in use for thatpurpose is the object of the present invention.` and is accomplishedthereby by means of a peculiar arrangement of the nozzle or dischargingend of the air-pipe, whereby, in lieu of causing the air to issue insuch a body or stream from the pipe that the oil could only come inContact with its exterior surface, it isdischarged from its pipe throughan annular opening or orifice, communication with theinterior of whichairblast is had by the oil through any suitablyarranged aperture orapertures connecting it with the oil-chamber, thus necessarilyincreasing the suction and drawing up proportionallymore oil from thewell than heretofore possible.

I have also made other improvements,which will be hereinafterparticularly alluded to.

In the accompanying drawings my improvements are illustrated, Figurelbeing a central longitudinal vertical section, and Fig. 2 a transversehorizontal section in planeo'f line X X, Fig. 1; Figs. 3 and 4detailviews.

a a in the drawings represent an air-pipe,

made of any desired size and material, and of sufficient length to reachnearly to thebottom of the petroleumfwell inwhich the apparatus is to beinserted. To the upper end of" this air-pipe anyA suitable air-pump `is:to be at; tached, and its lower end isbent into theform` of an insertedsiphon,and passes into the lowerl end of oil-pipe b b and a shortdistance upward in the same, terminating in a peculiar p shaped nozzle,c c, to `be presently; described.;A

The oil-pipe b b rests on the bottom of the well, and is to be made ofsuflicientlengthto extend to or above the t'op of` thesame; d d i and e,a series of apertures inllower end of pipe b b, through which the oilpasses` from the well into the same.

The nozzle o c is made asfollows, viz:

f f is a hollow cylindrical drum of` consid-` erably less diameterthanthe oil-pipe b b, t

open at each end to the oil in same, and placed vertically within itsaxis, in which position it is heldy by short radial arms or pins gig,&c`. In the upperend of drum f and` around its`central opening,` la,is'an annular orifice or aperture, Z, extending nearlythrough itslength, and communicating at its lower endl by means of two shortconnecting-pipes, fm m, i y

with the upper end of air-pipe a a. t

n is a conical-shaped plug attached to lower end of a short verticalrod, :0, `hung at its upper end in the center of a fixed cross-bar, p,

of oil-pipe b. The plugfn is over the nozzle c c, and has its apextoward the same.

c e is a ring on lower endof oil-pipe b 419,011 upper edge of which theair-pipe `a a rests, said ring being loose on itspipe, so as to` beeasily moved up or downupon the same, and

thus by raising or lowering the pipe ct abringz its air-nozzle c c asnearto or as far from the conical plug n as` may be desired, a set-screwor any other suitable device being used to securely hold it in thedesired position.`

Into the pipe aa air is forced under great plug n and pipe b, andthewhole length ofthe pipe, issuing at the top, and there delivering theoil into any proper tank. or vessel.`

From the above description it is evident l )hat by my improved apparatusthe oil not )nly cornes in contact With the exterior sur- Face of theair-blast, as heretofore, but through its interior communication, s,with theinterior surface of the salue, thereby proportionally increasingthe suction of the oil by the blast, and causing a corresponding largerquantity of oil to be delivered from the Well through its oil-pipe.

The nozzle c c can be niade of Various shapes other than hereindescribed, it being only necessary that its discharging-orifice shouldbe of an annular shape, and that thereshould be an interiorcommunication for the oil in the pipe to the saine. It is also evidentthat the conical plug n serves not only as a guide to the air-blast'7but also relieves the backward pressure of the oil upon the same, as itsbase is a support and sustains a column of oil having a diameter equalthereto.

I do not claim the use of steam or compressed air for elevating oil orother liquids.

Having thus described my invention, I claimr as new and desire to secureby Letters Patent-- l. The use, in apparatus employed for the raising ofliquids from great depths or to great heights, of an annularshapedorifice or opening for producing an air-blast in the same, saidorificebeing so arranged as to allow the liq uid to be raised to come incontact with both the exterior and interior surfaces of the airblast,substantially as described, and for the purpose specified.

2. In combination with the nozzle c c, having an interior oil-passage,the conical plug n, or its equivalent, arranged and operatingsubstantially las and for the purpose specified.

3. Adjusting the height of the nozzle of the air-pipe in the oil orliquid pipe, the same consisting in the use of the movable plate or ringe e, arranged and operating substantial] y as described.
